  • Patent number: 11482142
    Abstract: Systems are configured for facilitating light leak correction for a display device. The systems are configured to obtain a color value for a pixel and obtain a light leak value associated with the pixel. The light leak value is based on a measured light leakage associated with a color filter of a display device configured to display the pixel. Systems are also configured to generate an updated color value for the pixel by applying a light leak compensation operation to the color value for the pixel. The light leak compensation operation uses the light leak value as an input for modifying the color value to compensate for light leakage that may otherwise occur when displaying the pixel on the display device. Systems are also configured to trigger display of the pixel on the display device using the updated color value.

  • Patent number: 11314330
    Abstract: An electronic device detects, on a touch-sensitive surface, a user input directed to a user interface element associated with a respective operation, for example in a user interface for a locked mode of operation of the device. A first portion of the user input includes an increase in intensity of the contact followed by a second portion of the user input that includes a decrease in intensity of the contact. In response to the user input, the device displays a transformation of the user interface element, wherein a degree of the transformation is determined based on an intensity of the user input. If the user input satisfies feed-forward criteria, including a requirement that a characteristic intensity of the contact increase above a feed-forward intensity threshold, the device generates a first tactile output without performing the respective operation. Otherwise, the device generates a second tactile output and performs the respective operation.
